I don't know about that part. At least I haven't noticed that. She tends to hit open stance off her backhand wing which is good for going on the offensive but you sacrifice some control in the process. Her backhand is her best shot though. Her forehand can be hot or cold while her serve is not much of a strength. She's a good lateral mover but her vertical movement can improve a bit.

What I noticed is if she has to move backwards some when moving laterally (forcing shot to her) vs. moving just laterally (not as forcing). Or maybe it is just moving laterally when she should move backwards and laterally and so is late or hits a weak shot - not getting behind the ball. It is a very good backhand when she only has to move a little.
